摘要 为研究机载火控雷达对空目标成像和识别能力,需要通过仿真获取数据支持。针对机载火控雷达对空目标成像时,运动传感器对运动目标宽带探测的特点,建立载机和目标的飞行特性运动模型,通过姿态解算求取任意时刻雷达波对目标的入射角,建立目标的三维模型拟合目标几何外形,利用高频电磁计算模拟不同雷达视角条件下一定带宽范围内目标的多频点RCS数据,将目标的静态散射特性数据拓展成动态散射序列,并考虑复杂自然环境和电磁环境的对回波的影响,为进一步研究机载火控雷达对空目标成像能力和成像条件提供数据支撑。 To research the imaging and recognition ability of the Airborne Fire Control Radar for Air Object,support was needed to get wideband ehco data by simulating.Considering the characteristic of locomotive sensor to locomotive target wideband exploration about Air Object to Airborne Fire Control Radar,the dynamics model of the carrier and the target was improved.And with gesture transforming,the incidence angle of the radar beam was obtained.By modeling the target and through the electromagnetic calculation,the wideband echo was gained in a given angle of view and the scatter features sequences was extended from static state to dynamic state.And the infection of environment was considered at last.The results of the simulation provide the foundations to imaging and target recognition.
